Introduction

SCS
-PTC, the Original
Thank you for having decided to purchase the
SCS
-PTC-IIex. The
SCS
-PTC-IIex is the
original, develped by those people that created PACTOR and PACTOR-II. Only from
SCS
you receive the best possible support. The concentrated knowledge of the PACTOR- engineers
is available to you.
The
SCS
-PTC-IIex is the optimized device for modern, digital short wave communication as,
additional to PACTOR, all the other HF modes like AMTOR, RTTY, CW and a lot of others
are supported.
The PTC-IIex reacts on PACTOR- and AMTOR-calls and answers automatically in the
correct mode
. Because of these outstanding features the
SCS
-PTC-IIex is the best device for
all of those people that do not only want to use PACTOR, but also AMTOR. Also in mailbox
systems the features of the
SCS
-PTC-IIex can be utilized for best performance.
1.2
Requirements
To operate PACTOR, a transceiver capable of switching between transmit and receive within
20 ms is required. Therefore any transceiver capable of AMTOR can also be used for
PACTOR.
To operate the
SCS
-PTC-IIex you need a computer or a simple terminal that provides an serial
interface compatible with the RS232 (V24) standard. If you use a computer you need a
appropriate terminal program to operate the serial interface with the following parameters: 8
bit, no parity and 1 stopbit. The baud rate in the range between 2400 and 115200 Baud is
automatically sensed by the PTC-IIex (Autobaud operation).
Many modern computers (especially laptops) do not have a serial COM connector. For these
computers a USB to RS232 converter can be purchased from most computer stores and
SCS
representatives. With the help of this adapter you can easily operate the PTC-IIex with the USB
interface of your computer.

About this manual
This manual contains information on the installation and operation of the
SCS
PACTOR
Controller. The shortform for PACTOR Controller is PTC and is used in this manual
alternatively.
The manual may be used as a reference manual for the PTC commands and as a hardware
reference.
show how to "quick start" the PTC-IIex. Section
gives basic introduction
about PACTOR and PACTOR-II. Section
shows the command structure and operation of the
PTC.
You should additionally read sections
. Here it is explained how the audio
output signal from the PTC-IIex is adjusted for FSK and PSK operation.
